No medical aid replacent cards

I'm a Classic Comprehensive Client of Discover and paying a fortune for medical aid. I Ordered replacement Medical Aid card on the 4th Of January. Got a reference number (WRefNo#*** MailRef#*** )from Discovery stating the cards will be delivered with in 7 days. I escalated it again on the 24th of February. I was assured the cards will be couriered to me and I will receive it the first week of March. Discovery is still not able to provide me with a Courier waybill number meaning that they haven't even received my card to courier.

On the 24th of Feb my Wife was declined service at the XRAY's because they don't accept Digital medical aid cards. They had to leave to collect my card so that they can get assistance.

What happens it the case of an emergency? If we cannot offer proof of medical they wont be able to receive the correct treatment that I pay for?

THIS IS UNACCEPTABLE SERVICE AND DISCOVERY DOESN'T CARE.

Miss one payment with Discovery and they cancel my membership. But they can do what ever they want.
